AWS Cost Explorer Service
Cost Management APIs


Retrieves the reservation utilization for your account. Master accounts in an organization have access to member accounts. You can filter data by dimensions in a time period. You can use GetDimensionValues to determine the possible dimension values. Currently, you can group only by SUBSCRIPTION_ID.

Request Syntax

{ "Filter": { "And": [ "Expression" ], "Dimensions": { "Key": "string", "Values": [ "string" ] }, "Not": "Expression", "Or": [ "Expression" ], "Tags": { "Key": "string", "Values": [ "string" ] } }, "Granularity": "string", "GroupBy": [ { "Key": "string", "Type": "string" } ], "NextPageToken": "string", "TimePeriod": { "End": "string", "Start": "string" } }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.


Filters utilization data by dimensions. You can filter by the following dimensions:

  • AZ












GetReservationUtilization uses the same Expression object as the other operations, but only AND is supported among each dimension, and nesting is supported up to only one level deep. If there are multiple values for a dimension, they are OR'd together.

Type: Expression object

Required: No


If GroupBy is set, Granularity can't be set. If Granularity isn't set, the response object doesn't include Granularity, either MONTHLY or DAILY. If both GroupBy and Granularity aren't set, GetReservationUtilization defaults to DAILY.

Type: String

Valid Values: DAILY | MONTHLY

Required: No


Groups only by SUBSCRIPTION_ID. Metadata is included.

Type: Array of GroupDefinition objects

Required: No


The token to retrieve the next set of results. AWS provides the token when the response from a previous call has more results than the maximum page size.

Type: String

Required: No


Sets the start and end dates for retrieving Reserved Instance (RI) utilization. The start date is inclusive, but the end date is exclusive. For example, if start is 2017-01-01 and end is 2017-05-01, then the cost and usage data is retrieved from 2017-01-01 up to and including 2017-04-30 but not including 2017-05-01.

Type: DateInterval object

Required: Yes

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.


The token for the next set of retrievable results. AWS provides the token when the response from a previous call has more results than the maximum page size.

Type: String


The total amount of time that you utilized your RIs.

Type: ReservationAggregates object


The amount of time that you utilized your RIs.

Type: Array of UtilizationByTime objects


For information about the errors that are common to all actions, see Common Errors.


The requested data is unavailable.

HTTP Status Code: 400


The pagination token is invalid. Try again without a pagination token.

HTTP Status Code: 400


You made too many calls in a short period of time. Try again later.

HTTP Status Code: 400


The following is a sample request and response of the GetReservationUtilization operation that allows you to retrieve your RI utilization for all t2.nano instance types from 2017-01-01 to 2017-05-01:
